Description

The invention relates to a lamp having a light opening having light carrier, a lamp cover for covering the lamp opening and a closure device with at least one closure for fixing lamp holder and lamp cover to each other, wherein the closure is a snap mechanism with a first closure element, the locking in a closed position on the Luminaire cover or acts on the light carrier and against a spring force of a spring assembly from the closed position to an open position in which the closure the lamp cover and the light carrier releases, can be brought, and with a release of the closure in the open position against the spring force on the Closure acting eccentric assembly comprising an eccentric with eccentric shaft.

Such lights are widely known. As a luminaire cover, they often have a grid and / or a transparent panel. The light carrier may for example be a light housing and / or a framework, which limit a receiving space for provided bulbs. The luminaire cover must be removed, for example, to replace defective bulbs of the luminaire. Usually, the attachment of the lamp cover via hinges attached on one side, which are attached to the light carrier and the lamp cover the same connecting, while on an opposite side, for example, releasable fastening tabs are arranged. Here, the installation of the lamp cover to the light carrier is complicated, which, for example, in the arrangement of the lights on a sports hall ceiling due to the present there large room height, further difficult. In public space, such as used in sports halls, are on the grid and / or the visor special strength requirements, such as ball throw safety, provided by which the light cover must be designed accordingly stable and therefore heavy. Thus, the assembly and replacement of luminaires are further complicated. In addition, the locking parts, such as hinge and fastening straps, are above the lamp. These can be weak points under extreme load of the lamp under ball bombardment. Furthermore, they can pose a risk of injury. After all, they oppose a shapely design.

DE 10 2007 009 548 A1 describes a generic lamp with a lamp opening having a light carrier, a lamp cover to cover the lamp opening and a closure device with at least one closure for fixing lamp holder and lamp cover together. The closure has a snap mechanism with a closure element which engages lockingly in a closed position on the light carrier and against a spring force of a spring arrangement from the closed position can be brought into an open position. The coupling of a force required for unlocking the closure force via an eccentric eccentric. The closure element is designed as elastically deflectable latching element. The eccentric is also elaborately formed of three parts. A disadvantage is the complex structure of the lamp with the closure or the closure and thus the complex assembly of the lamp. Furthermore, there is no sufficient ball throw safety, in particular against obliquely rising balls.

Out DE 975 421 C is a luminaire with luminaire housing and cover known. The closure of the lamp has a camshaft with a cam on which a pivoting hook is arranged to pivot directly about a parallel spaced apart from the axis of rotation of the camshaft arranged pivot axis. This Schenkharken can be converted over a rotation of the camshaft like a toggle in a closed position in which the Schwenkharken presses the cover via a seal against the lamp housing. Again, there is no sufficient ball throw safety.

DE 74 25 333 U and DE 1 876 602 U each inform about a non-generic lamp with a conventional snap-lock, which is automatically solvable only by a relative movement of the lamp cover and the lamp housing. Thus, the closure can easily open under external shock load, which is why such lights can not have sufficient ball impact safety.

WO 95/19306 A1 discloses a refuse container with a snap mechanism having a locking element, wherein the closure element is actuated via an eccentric arrangement.

The invention is therefore an object of the invention to provide a lamp of the type mentioned, which is easy to install and the light cover is easily folded away and / or removable. Furthermore, a Ballwurfsicherheit should be guaranteed.

The stated object is achieved by the features of claim 1. Advantageous developments are described in the appended subclaims. The object is achieved in particular by the fact that the closure has a closure carrier, by means of which the closure on the light carrier or is fixed to the lamp cover, wherein the first closure element in a direction of movement is arranged variable in position on the closure carrier and the eccentric is rotatably mounted with its eccentric shaft perpendicular to the direction of movement of the first closure element in or on the closure support.

Thanks to the snap mechanism, the light cover can be brought to their mounting on the light carrier against the example fixed to the sports hall ceiling light carrier with the closure and fixed without the use of an additional tool. The luminaire cover can in this case be guided against the closure so that a force acting against the spring force is introduced into the closure, whereby the closure opens. The luminaire cover can thus be brought into their prescribed installation position with simultaneous opening of the closure, in which then engages the lock under at least partial spring relaxation locking the lamp cover and fixes the same in the prescribed mounting position. The assembly can, since only the light cover must be pressed against the closure, which locks on the cover or engages in the same interlocking, done with one hand. This can be easily pressed under, for example, manual contact pressure for sealing contact against a proposed gasket bed and fixed in position on the gasket bed under contact pressure. This allows a particularly tight connection of the lamp cover and light carrier. This can be achieved in conjunction with a closed to the luminaire opening, light carrier effective tightness. This can, when marked as protection, for example, achieve dust tightness according to IP50 or water jet protection according to IP65.

The closure may have a closure carrier, by means of which the closure on the light carrier or the lamp cover can be fixed or fixed. The closure may further comprise a first closure element as part of the snap mechanism for engagement with the light cover or on the light carrier. The first closure element may be arranged to be variable in storage on the closure carrier.

Preferably, the lamp cover in a mounting direction with at least one component perpendicular to the opening axis of the lamp opening via the same on the light carrier can be mounted. The first closure element may have a Abgleitebene for guiding the lamp cover and the force introduction of a force against closing direction in the first closure element. Advantageously, the Abgleitebene is arranged so that it has a directional component against mounting direction and with a directional component in the closing direction. Thus, by transferring the lamp cover against the first closure element, a force can be introduced into it via the Abgleitebene, which has at least partially against the closing direction. As a result, the closure against spring force can be moved to the open position.

Preferably, the first closure element strikes against an intended stop in the open position. The first closure element may preferably rest in the open position under spring bias on the stop. As a result, the first closure element, when it is no longer pressed against the stop in the open position, can be automatically moved into its closed position with at least partial relaxation of the spring. That is, when the first shutter member is forced back during assembly of the lamp cover by the same in the open position, it automatically snaps into its closed position when the lamp cover has reached its intended installation position in the lamp. Since the operation of the closure when mounting the lamp cover can be done solely on the lamp cover, the lamp cover can be mounted with one hand and without the use of an additional tool to the light carrier. The stop can be formed by means of a side surface, preferably an outer side surface. The stop can be designed to adapt to the intended light cover or to the lamp provided adjustable.

Preferably, the first closure element is arranged at least almost completely in a space bounded by luminous carrier and luminaire cover. Thus, the first closure element can be at least almost completely hidden and thus protected in the luminaire. In addition, this can be achieved an increased ball impact safety, that is, the first closure element can not be operated unintentionally. Furthermore, this allows a pleasing design of the lamp.

In a preferred embodiment, the first closure element is designed as a snap hook. The snap hook may have a hook opening for locking receiving a second closure element, which is arranged on the lamp cover or on the light carrier. The snap hook can thus securely surround the second closure element in the closed position. Preferably, the closure element or the snap hook is in its closed position under spring tension on the lamp cover or on the light carrier. Thus, the closure elements can securely interlock. The snap hook can so around the pivot axis be arranged pivotably so that it overlaps with respect to a mounting direction from the outside perpendicular to the lamp opening on the same on the second closure element.

According to a conventional hook shape, the hook may have a hook shank, which merges into a round arch delimiting the hook opening, the hook opening having a passage for engagement in the second closure element to the hook shank. Preferably, the round arch in the open position and in the closed position against mounting direction. This allows the round arch to serve as an inclined plane. At this, the second closure element on its way to the passage, while pushing back the snap hook into its open position slide into it until it reaches the passage into the hook opening and reaching it in this passage can be locked with movement of the snap hook in its closed position. The light cover can be pressed for mounting, for example, manually against preferably a sealing field of the light carrier or of the housing, wherein the hook can set the light cover under at least partial preservation of this press-fitting on the sealing field. For this purpose, the hook also bias the lamp cover in addition. As a result, particularly high tightness, for example, according to the types of protection described above, can be achieved.

The second closure element may be formed as an eyelet, rod, hook or the like, that is, as a mechanically rod-like acting portion which is received by the hook opening. Preferably, the second closure element is designed in the form of an outer bead. For this purpose, the lamp cover may have an outer frame in which its disc or a grid is arranged. The light cover can also be a cantilever grid. The frame may be an extruded aluminum profile with the outer bead. Thus, the outer bead can extend over the longitudinal extension of the frame or circumferentially around the lamp cover. However, the bead can also be provided only in an intended circumferential region of the lamp cover for the attack of the first closure element or the snap hook. So that the snap hook can engage freely on the outer bead, the outer bead with respect to its cross section, at least with a directional component against the closing direction of the lamp cover wegerstrecken.

The closure is preferably arranged in the luminaire such that it does not project beyond the luminaire with its first closure element. Thus, the closure element, for example, as a result of a ball throw against the light, not be operated accidentally. Preferably, the lamp is designed so that the second closure element is completely covered in the installed position of the lamp cover in the open position and / or closed position.

For actuating the first closure element, the snap mechanism may have an eccentric arrangement with an eccentric. The eccentric can act against the spring force on the closure for unlocking the closure in the open position. The eccentric can thus couple a counter force to the spring force in the first closure element.

For this purpose, the eccentric can have an eccentric shaft with a lateral cam. The eccentric shaft can be mounted rotatably in the closure carrier perpendicular to the direction of movement of the first closure element or perpendicular to the pivot axis of the snap-action hook. The eccentric has the advantage that the required force on the side cam, that is, via a lever arm, can be coupled into the first closure element. Furthermore, the eccentric can act on the first closure element in both possible directions of rotation of the eccentric shaft. The eccentric can thus have a zero position, in which it is force-mechanically released from the first closure element or from the snap hook at least almost or the first closure element is in the closed position. From this zero position out the eccentric shaft can be rotated with simultaneous displacement of the first closure element or the snap hook from the closed position to the open position. It can be provided that this process is possible in both directions of rotation of the eccentric shaft, which facilitates the assembly. Preferably, in both directions of rotation in each case a same working angle of rotation is required. The working angle of rotation can be <120 °, preferably <90 ° and ideally by 45 °.

For the eccentric an over-rotation can be provided by means of which over-rotation of the eccentric can be prevented beyond the open position addition. For this purpose, the first closure element or the hook in the open position against an outwardly facing side surface of the eccentric so abut that the eccentric is blocked against further rotation beyond the open position. Preferably, with the blockade of the eccentric at the same time the first closure element or the hook is blocked against further pivoting beyond the open position, so that this side surface of the eccentric, against which the hook abuts in the open position, at the same time may be the abutment described above the first one Closing element in the open position is loosely applied.

The eccentric shaft can protrude with an actuating end at least to near the outside of the lamp or the same by preferably projecting a small amount. The operating end may be accessible for its actuation via a provided, preferably closable opening from the outside. The actuating end can be designed such that it can be actuated with a conventional tool, such as a screwdriver, open-end wrench, ring spanner and the like, preferably with an Allen key. This in turn ensures a high ball impact safety. It may also be provided a special tool for actuating the lamp closure to prevent unauthorized operation of the lamp shutter.

Preferably, the closure has two snap hooks which can cooperate to lock the lamp cover to the light carrier. The snap hooks may be spaced parallel with respect to the pivot axis and arranged in alignment therewith. Furthermore, they can be rigidly connected to one another in terms of mechanical strength. For this purpose, both can be arranged rotatably on the pivot axis and / or rigidly connected via a connecting element, preferably cohesively, to one another. The connecting element can also serve for spacing the two snap hooks from each other. Thus, the snap hooks can be arranged synchronously to each other pivotally mounted on the pivot axis. The use of two parallel spaced snap hooks allows a mechanically stable closure of the closure. Preferably, the two snap hooks are arranged with respect to the eccentric shaft on both sides thereof and equidistant from the same, wherein the connecting element is preferably guided close to the eccentric.

The connecting strap can strike against the stop when it reaches the open position. For this purpose, the eccentric having an at least substantially axially facing mounting direction side surface as a stop. With rotation of the eccentric from the zero position, the connecting plate can be pressed against the closing direction to the rear while pivoting the snap hooks and, due to the pivoting, at the same time laterally guided on the cam, preferably on an at least substantially axial edge of the cam so that they slide in Mounting direction can strike against the stop. As a result, a further rotation of the eccentric is blocked in the sense of over-rotation protection. The edge may be formed with respect to the mounting direction as a ramp or slope and act as an inclined plane.

The cam may have a semicircular cross-sectional area with two edges, wherein the connecting tab may slide on each of the against closing direction twisting edge of the cam. This construction allows the snap hook can be pivoted in both directions of rotation of the eccentric from a zero position to the open position, with an over-rotation of the eccentric is avoided beyond the open position of the snap hook.

The snap hook can be made in a simple manner as a stamped part of a metal sheet. Preferably, the first closure element with two snap hooks and the connecting element is made from a correspondingly folded sheet metal. Similarly, the closure housing can be made of a folded sheet metal.

The spring arrangement may have one or more springs which are suitable for introducing a spring force acting in the closing direction into the first closure element. The spring assembly may comprise a coil spring rotatably mounted on the pivot axis and supported at one end on the pivot hook and at another end on the latch support. The coil spring may have opposing spring windings. For this purpose, the coil spring can have two spring windings with end-side support ends, which are separated by a central region, for symmetrical support on the first closure element or on the snap hook, wherein the spring can be supported by the center region on the light carrier. Advantageously, among other things, because of a simplified assembly, a leaf spring can be used, which is fixed at one end to the closure carrier and at the other end under initiation of the effective closing force spring force on the first closure element, preferably under formation of a lever arm, supported. The spring assembly can couple the spring force via a lever with respect to the pivot axis in the snap hook. Preferably, the closure carrier or the closure is arranged in the light carrier in such a way that it mechanically stabilizes or stiffens the light carrier. Thanks to this stiffening of the light carrier with respect to its strength or torsional stiffness can be correspondingly smaller dimensions. The closure can be arranged on the outside of the housing. The closure may preferably be arranged on the inside of the light carrier as a reinforcing element or stiffening rib. He can at least about a pointing away from the lamp opening depth dimension of the lamp housing or in the mounting direction be set on a side surface or a room edge of the light carrier. It can form at least a portion of an intended framework of the light carrier. The closure can also serve as a carrier or fixation point for other lighting components.

Depending on the luminaire geometry and / or the weight of the luminaire cover, at least two closures may be provided per luminaire cover. These can be arranged circumferentially equally spaced with respect to the associated lamp opening. The light carrier may have, for example, a quadrangular light opening. Here, two with respect to the lamp opening diametrically opposite closures or four arranged in the room edges of the lamp housing closures can be provided. If the luminaire has a round luminaire opening, then at least three closures, which are preferably circumferentially equally spaced with respect to the luminaire opening, can be provided.

In a preferred embodiment of the second closure element, its cross section may be round, preferably circular. As a result, the second closure element accommodated in the hook opening of the snap-in hook can be rotated in the hook opening. For example, to replace luminaires of the lamp, the lamp cover can be folded away from the light carrier side. For this purpose, for example, two-sided attachment of the lamp cover, the one or more fasteners of one side can be solved while the other side remain in the closed position. Thanks to the cross-sectional configuration of the second closure element, the light cover can be folded away by rotation of the second closure element in the hook opening of the light carrier and remain on the light carrier. This is particularly advantageous for highly mounted lights, since the light cover for changing the lighting fixtures can hang on the light carrier and does not need to be stored.

The luminaire may be at least partially assemblable on the basis of a kit, wherein the kit has at least light carrier, lamp cover and closure device with at least one closure. The kit may include, for example, closures of different design.

• 11 a to c schematic side views for mounting the luminous cover or for replacing a lamp body of the lamp.

In the 1 to 3 . 7 to 9 and 10 a to d are various views and sections of several embodiments of a lamp 1 shown. The lamp 1 has one as a light housing 2 trained light bearer 3 on top of a recording room 4 limited for a lamp body, not shown here. The recording room 4 is open to the outside through a light opening for the emission of light, through a light cover 6 is covered. luminaire housing 2 and light cover 6 are by means of a closure device 7 fixed to each other. The closure device 7 has at least two closures in the embodiments shown here 8th on. Every closure 8th includes a snap mechanism 9 who is in an in 4 and 6 locked position shown locking in the embodiments of the lamp shown here 1 on the light cover 6 attacks. This is in the 3 and 9 , each one an enlarged detail according to 2 or. 8th represent shown. The snap mechanism is against a spring force F a spring arrangement 10 from the closed position to an open position changeable, in which the closure 8th the light cover 6 releases.

In the 4 to 6 are same views and cuts of the lock 8th shown in two different embodiments, this being only by the design of the spring assembly 10 differ. In 5 becomes the lock 8th shown in the open position.

Like that 4 to 6 clearly removable, the closure points 8th a closure carrier 11 with a closure housing 12 and a lock support 13 on, with the lock support 13 , as in the longitudinal sectional views according to the 4e . 5e and 6e shown, angled and extending with a first end section 14 in the lock housing 12 extends into it. The lock support 13 has an angled second end portion 15 on, with which the shutter 8th inside in the luminaire housing 2 is determinable. The closure 8th also has a first closure element 16 as part of the snap mechanism 9 to attack the light cover 6 on. The first closure element 16 is in the embodiments of the lamp shown here 1 or the closure 8th as a snap hook 17 formed, which is pivotable about a pivot axis s to the lock carrier 11 or here on the closure housing 12 is arranged. The pivot axis s runs in installation position of the closure 8th parallel to the luminaire opening 5 , where the shutter 8th so in the light carrier 3 arranged is that the snap hook 17 with his hook opening 18 to the light opening 5 or the lamp cover 6 is facing. As in particular the 3 and 9 Removable, points the lamp cover 6 a second closure element 19 in the form of a bead 20 in the closed position in the hook opening 18 is included. Is the first closure element 16 or the snap hook 17 in his in 5 shown open position in which the snap hook 17 in installation position of the closure 8th from the light cover 6 is pivoted away, so is the second closure element 19 or the bead 20 released at this point.

The spring arrangement 10 here includes only one spring 21 , The spring 21 is in the embodiment of the closure 8th according to the 4 and 5 as a leaf spring and in the embodiment according to 6 designed as a helical spring. In both cases, the spring is supported 21 with one end 22 below the snap hook 17 and with another end 23 to the lock carrier 11 from. Here's the other end 23 the spring formed as a leaf spring 21 at the closure carrier 11 set while the other end 23 the designed as a coil spring spring 21 is mounted pivotably on the pivot axis.

As purely schematic in the 11a and b is the lamp cover 6 in a mounting direction m perpendicular to the luminaire opening 5 mountable over the same. With abutment of the light cover 6 at the snap hook 17 becomes the snap hook 17 against the spring force F pushed back from its closed position to the open position. At the same time, the luminaire cover 6 reached its prescribed mounting position, the bead 20 in front of the hook opening 18 has arrived, whereupon the snap hook 17 under partial relaxation of the spring 21 over the bead 20 snaps. Thus, the light cover 6 with one hand and without further tools on the light carrier 3 to be assembled. In transfer of the required force to push back the snap hook 17 through the light cover 6 slide snap hook 17 and bead 20 according to the principle of the inclined planes from each other. Here, the snap hook points 17 the upper side in its rounding one against mounting direction m and in the closing direction sr pointing, curved plane 24 on, at the bead 20 on the way to the hook opening 18 by pushing back the snap hook 17 slides into the open position.

In the embodiments of the closure shown here 8th are two snap hooks 17 provided, with respect to the pivot axis s are spaced parallel and aligned with each other and by means of one here as a connection tab 27 trained connecting element are materially interconnected. That's what the shutter takes 8th at two spaced points and thus mechanically more stable to the bead 20 on.

For immediate release of the closure 8th has the snap mechanism 9 an eccentric arrangement 25 with an eccentric 26 on. The eccentric 26 includes an eccentric shaft 26.1 with a side cam 26.2 , The eccentric shaft 26.1 is perpendicular to the pivot axis s or in installation position perpendicular to the mounting direction m rotatable on the closure housing 12 stored. The shape of the cam 26.2 is particularly in the cross-sectional views according to the 4d . 5d and 6d seen. The cross section of the cam 26.2 is approximately semicircular with rounded edges 26.3 educated. In 6 with the closed position of the closure 8th is the cam 26.2 mechanically stable flat on the connecting lug 27 on. Will the eccentric 26 operated, that is, is the eccentric shaft 26.1 turned left or right, so presses the cam 26.2 the connecting strap 27 with the two snap hooks 17 against closing direction sr back. As in 5d with the open position of the shutter 8th shown, the eccentric shaft 26.1 only a working angle ß twisted by about 45 °, in which the cam 26.2 with regard to their rotation unstable at the connecting link 27 is applied. From the point of view alone, it becomes clear that releasing the eccentric shaft 26.1 the two snap hooks 17 by the spring force F snap back into their common closed position while the eccentric 26 back in the 4d and 6d shown, mechanically stable position is turned back. Due to the symmetrical design of the eccentric 26 is it possible the eccentric shaft 26.1 in both directions to rotate in each case the same working rotation angle β, whereby the first closure element 16 is moved into its open position.

Against over-rotation of the eccentric 26 about the working angle of rotation ß There is also an overspeed protection 28 with a stop 29 provided against the here the connection tab 27 strikes with reaching the open position. The stop 29 Here is an axial against mounting direction m facing side surface of the eccentric 26 , With rotation of the eccentric 26 from the zero position becomes the connecting tab 27 under pivoting the snap hook 17 against closing direction sr pushed backwards. At the same time the connecting strap slides 27 due to the pivoting laterally at one of the edges 26.3 the cam 26.2 from and in mounting direction m against the attack 29 , The cam 26.2 has two edges with its semicircular cross-sectional area 26.3 on. From the view it can be seen that the connecting strap 27 in each case against the closing direction sr twisting edge 26.2 slides.

The eccentric shaft 26.1 protrudes in this embodiment with an actuating end 30 slightly above the lock housing 12 and, as in the detail enlargements of the 3 and 9 seen with a minimal amount over the closure housing 12 out. The end of the operation 30 has an operating opening at the front 31 on, which here has a conventional hexagon socket for a hexagon socket key, not shown here. Thus, the eccentric 26 Although operated with a conventional tool, but not triggered by a shock, such as by a ball throw, unintentionally.

The two snap hooks 17 are in these embodiments at the end in the region of the pivot axis s with an additional, parallel to the other connecting tab 26 extending connecting strap 26.1 connected. At this connection tab 26.1 grab the pen 21 with her end 22 on the bottom.

The light carrier 3 in the 1 to 3 illustrated embodiment of the lamp 1' has a transparent panel 32 on that in a frame 33 with the bead 20 is fixed. The frame 33 consists of an extruded aluminum profile and covers the bead 20 topside. In the embodiment of the lamp 1 according to the 7 to 9 is the light cover 6 as a grid 34 formed that the bead 20 having.

In the 10a to d, possible arrangements of closures are shown purely schematically. According to 10a are with an elongated lamp 1 two opposing closures 8th provided while in 10b on one side two and on the opposite side a closure 8th are provided. For a round light, according to 10c circular light 1 Be at least three closures 8th considered useful, which are circumferentially equally spaced. For a rather square lamp 1 according to 10d are four closures 8th provided, which are each arranged in the corners.

As from the arrangements of the closures 8th according to the 10a to d as well as from the 3 and 9 Immediately apparent are the closures 8th each edge and inside of the lamp housing 2 arranged, with the closures 8th over the second end portion 15 the lock support 13 in addition to the closure housing 12 fixed, screwed here. However, the screw connection is not shown. Furthermore, the closure extends 8th over the entire depth of the lock housing 12 , Thanks to these measures, the shutter can 8th at the same time as a reinforcing element for here the luminaire housing 2 serve, which in turn the luminaire housing 2 can be formed correspondingly thin-walled, yet to achieve a total sufficient strength, in particular connection stiffness of the lamp.

For example, to replace a light bulb, not shown here, the light cover must 6 thanks to the special design of the closure 8th not completely from the light carrier 3 be removed. The light cover 6 only has to be on one side of the closures arranged there 8th can be solved and can in the closures 8th be pivoted on the other side ( 11c) , This is the bead 20 in the hook opening 18 turned. For this purpose, the bead may be formed in the region or the areas of the latter closures by means of an edge opening, not shown here, to the luminaire cover towards a shaft around which the respective closure can rotate. In this area or these areas, the shaft may be made of a material of increased strength, such as metal.
